This paper extends recent work on decision tree grafting. Grafting is an inductive process that adds nodes to inferred decision trees. This process is demonstrated to frequently improve predictive accuracy. Superficial analysis might suggest that decision tree grafting is the direct reverse of pruning. To the contrary, it is argued that the two processes are complementary. This is because, like...

We reviewed retrospectively the outcome of the treatment by impaction grafting of periprosthetic femoral fractures around loose stems in 106 patients with Vancouver type-B2 and type-B3 fractures. Eighty-nine patients had a cemented revision with impaction grafting and a long or short stem. The remaining 17 had cemented revision without impaction grafting. Fractures treated by impaction grafting...

OBJECTIVE To compare outcome of patients with burns covering less than 15% of total body surface area(TBSA) undergoing early excision and grafting or delayed skin grafting. METHOD This was a non-randomized clinical trial including 54 patients with less than 15% TBSA burn referring to Ghotboddin Hospital of Shiraz. They were assigned to two study groups, each group including 27 patients: the e...

introduction: gold standard for alveolar cleft bone grafting is autogenous bone. advantage of adding the growth factors to the bone is established, so adding prf to the autogenous bone may have beneficial effects. methods:  platelet-rich plasma admixed with autogenous bone and as a biologic membrane over the bone grafted alveolar cleft was used. results:  autogenous bone in all (four cases) was...

background  many biomaterials are used during the open sinus lift surgery, beneath the elevated scheniderian membrane and maxillary sinus bony floor but the search for ideal material continues. methods  in the maxillary posterior atrophic ridges with the bone height less than four millimeters the open sinus lift surgery performed. the autologous platelet-rich plasma (prf) was used as the sole g...

BACKGROUND The increasing use of autologous fat grafting in breast cancer patients has raised concerns regarding its oncologic safety. This study evaluated patient outcomes and tumor recurrence following mastectomy reconstruction and autologous fat grafting. METHODS Retrospective chart review identified patients who underwent mastectomy followed by breast reconstruction from 2010 to 2015. Eig...

The study was designed to exploit the single photon emission computerized tomography (SPECT) to compare osteoblastic activity of two implant systems: an Endopore implant (Beaded implants) placed immediately into an extraction socket in conjunction with peri-implant autogenous grafting supplemented with a guided tissue regeneration (GTR) technique, and an Endopore implant placed immediately into...

Background Universally, anastomosis of the left internal mammary artery (LIMA) to the left anterior descending artery (LAD) is accepted as the gold standard in coronary artery bypass grafting. The use of the right internal mammary artery (RIMA) for grafting the LAD has recently emerged as an alternative to avoid composite configuration in multiple arterial grafting using bilateral internal mamm...

Reconstructing scalp defects can be challenging for a plastic surgeon. For this purpose, different procedures such as primary repair and coverage with skin grafts or flaps can be considered. Sometimes, the external table of the skull can be removed completely to the diploic space. At the same time or after the formation of granulation tissue, the diploic space can be covered with split-thicknes...

The development of vegetative propagation programs Araucaria angustifolia still lacks on information about genetic factor that may influence its success. We aimed to evaluate how mother tree sex and provenance grafting So, we collected orthotropic branches from 26 trees male female, a clonal garden established matrices different provenances, carried out an experiment using patch technique. Graf...
